Dear Mr. Haering,

Thank you for posting your request on History Hub!

The Abraham Lincoln Papers are at the Library of Congress.  Inquiries about these records may be directed to their Ask a Librarian. Also, the Abraham Lincoln Presidential Library and Museum, which is not affiliated with the National Archives, may be able to assist you with your search.

We hope this is helpful. Best of luck with your research!
